前經長黃營杉接任大葉大學董座
In broadcast engineering, a panel antenna is a directional antenna that is widely used to obtain a wireless Internet connection.
Directional antennas receive and broadcast a signal in only one direction, resulting in better signal quality.
Panel antennas, for example, are used in underdeveloped countries to improve the range and functionality of wireless Internet networks.
A panel antenna is shaped like a panel and is typically fixed on a mounting bracket on the exterior or inside of a building. It can also be mounted on a swivel mount, allowing the user to adjust the antenna for optimal signal reception. This type of antenna is usually one-directional, with less mobility side-to-side and up-and-down than an omnidirectional antenna, which can swivel and entirely change its location. Two U-bolt brackets and waterproof were supplied in one piece of packing
【記者 劉嘉菲／台北 報導】前經濟部長黃營杉，6月2日在大葉大學董事會董事長遴選會議中，獲選榮任大葉大學董事長一職，國內企管界資深教授再出江湖，協助大葉大學校務發展。黃營杉教授歷任經濟部長、台電公司董事長、台灣菸酒公司董事長等要職，亦擔任國立臺北大學商學院首任院長，為國內企管學界領域之翹楚，擁有的門生眾多，許多門生目前都在全台各大之大專院校任教，積極陪育台灣優秀之企業管理相關人才。
黃營杉教授不僅在作育英才上著墨甚多，培育產業人才亦不遺餘力，像是國內知名半導體大廠崇越科技董事長郭智輝便是其門生，前經濟部工業局長賴杉桂、前文建會主委翁金珠等人亦是黃營杉的學生，可見黃營杉教授作育無數英才，為台灣各界培育許多中堅分子，強化台灣企管學子專業養成功不可沒。

Double Ridged Horn Antenna
Sort by:Select
The horn antenna is a broadband passive device, shaped like a pyramid horn, referred to as a TEM antenna, which guides the beam of radio waves at a precise frequency. FT-RF Double Ridged Horn antennas have frequency capabilities ranging from 400MHz to 40GHz depending on type and style. These series are characterized by a huge frequency range and extremely high input powers. With increasing frequency, the gain rises to a maximum of 18 dBi. At higher frequencies, the increased gain compensates for the increasing cable losses.
The advantages of Horn antenna:
- Wide bandwidth: Because the horn antenna has no resonant parts, it can function over a wide range of frequencies.
- Easy waveguide interface: These antennas are very easy to interface to waveguide due to their shape, but they can also be designed with a transition so that a regular coaxial feeder can be used.
- Easy to make, simple design.
The horn is suitable for both transmitting and receiving purposes, especially suitable for EMC and immunity test measurements.
Recommended Accessories
- Antenna Tripod: easy and fast-changing polarisation. 100% stable handling
- SMA Cable: High-quality special SMA cable
此次獲大葉大學董事會通過擔任董事長一職，黃營杉董事長表示，現任校長顏鴻森是他多年好友，顏校長本質學能俱佳，亦任職過行政院政務委員，在校務領導與管理上皆有目共睹，此次他願意接下董事長這重任，是因為創辦人夫人多次請託，希望他能夠協助顏校長在校務發展與推動上更加得心應手，更企盼能夠與顏校長一起帶領大葉大學全校師生一起向前行，讓學校的研究教學與學子專業養成等，都有很好與更寬廣的未來。
